3 Claims.

Our invention relates to a clamp structure for fastening the pedestal ofa device, such as a butter cutter, to a table or other support. While werefer to a butter cutter in the following description, it is understoodthat our improved clamp structure may be used in connection with thepedestal of any device where clamping to a support is desirable forholding the device rigid.

The broad objects of our invention are to provide a clamp of thecharacter described, which may be folded out of the way when thepedestal is moved, so that the inconvenience of a clamp dangling fromthe pedestal is avoided; and to provide means for holding the clamp inits folded or inoperative position.

The invention possesses other object and features of advantage, some ofwhich, with the foregoing, will be set forth in the followingdescription of our invention. It is to be understood that we do notlimit ourselves to this disclosure of spe cies of our invention, as wemay adopt variant embodiments thereof Within the scope of the claims.

Referring to the drawing:

Figure 1 is a side elevational view showing the clamp structure of ourinvention in operative position; and

Figure 2 is a similar view showing the clamp in inoperative position.

In devices mounted on pedestals, such as butter cutters, it is highlydesirable to clamp the pedestal to a support to give stability when thedevice is in operation. Since such devices are made portable forconvenience in moving them about, it is important that a clamp structurebe mounted as a permanent part of the pedestal to prevent loss. Stillanother and equally important consideration is that of keeping the clampout of the way, so that the pedestal may be moved freely about andpositioned on a shelf or other place of storage, without interference bythe clamp. Our improved clamp structure has all of these advantages.

In terms of broad inclusion, the clamp embodying our invention comprisesan arm pivotally mounted on the base of a pedestal, for movement from anoperative position depending from the base to an inoperative positionlying against the column of the pedestal above the base. Means are alsoprovided whereby the clamp arm may be shifted on its pivot to engage thearm with the base, so as to hold the clamp securely in its inoperativeposition.

In greater detail, our clamp structure .is mounted on a pedestal havinga base 2 for rest- Calif.; said Skoverski as- 1937, Serial No: 142,152

ing on a table or other support 3, and also having a column 4 forsupporting the head or body of a device, such as a butter cutter. Theclamp is of substantially G-shape, having a lower arm 6 with a thumbscrew 1 for clamping against the underside of the support 3. Upper arm 8of the clamp extends upwardly at an angle, and lies along the inclinedside of the pedestal base 2 when the clamp is in operative position, asshown in Figure 1.

Means are provided for mounting the clamp for combined pivotal andsliding movement on the base; whereby the clamp may be rotated upwardlyout of the way, and then shifted into a position of interlockingengagement with the base. For this purpose the clamp arm 8 is providedwith slot and pin connection, preferably formed by a slot 9 in the clamparm and engaging a pin I I held by suitable ears l2 formed on the base2. Of course this same arrangement could be obtained by stub pins on theears engaging grooves formed in the sides of the arms; or by a pin fixedin the arm and engaging grooves or slots in elongated ears on the base;or by other equivalent means.

By this arrangement the clamp may be rotated up against the column 4,and then dropped down against the base with the arm 8 caught between thepin and base. In order to insure a snug fit between the clamp andpedestal, the adjacent edge of arm 8 is curved, complementary to thecurved surface of the base; so that arm 8 is cradled in the lap of thebase, with the vertical edge of the clamp lying against column 4. Whenit is desired to use the clamp, it is only necessary to lift it out ofits locked position, and then rotate it down to the operative position.

We claim: 1

l. A clamp comprising a base, a clamp arm pivotally connected to thebase for movement between retracted and clamping positions, means onsaid arm and operable in the clamping position thereof for clamping thebase against a support, and means for mounting the clamp arm forslidable movement transversely of its pivot axis for positioning aportion of the arm against the base to lock the arm in retractedposition.

2. A clamp comprising a base, a clamp arm pivotally connected to thebase on a substantially horizontal axis for movement between upwardlyand downwardly extending positions, means on said arm and operable inthe downwardly extending position thereof for clamping the base againsta support, and means for mounting the clamp arm for slidable movementtransversely of its pivot axis for lowering a portion of the arm againstthe base to lock the arm against downpin whereby the arm may be shiftedtransversely ward pivotal movement. of the pin to position a portion ofthe arm against 3.
